The electrical properties of multi-component fluoride glasses which were based upon ZnF2 were studied by using complex impedance techniques at frequencies ranging from 5Hz to 500kHz. It was found that the conductivity of ZnF2-19.5BaF2-10InF3-10SrF2-10NaF-0.5PrF3 was equal to 1.16 x 10-7S/cm at 400K, and that the overall data could be described by:

σT (SK/cm) = 6.03 x 105 exp[-0.81(eV)/kT]

The conductivity of ZnF2-19.9BaF2-10InF3-10SrF2-10NaF-0.1PrF3 was equal to 1.45 x 10-7S/cm at 400K, and that the overall data could be described by:

σT (SK/cm) = 3.31 x 106 exp[-0.854(eV)/kT]

The conductivity of ZnF2-19.95BaF2-10InF3-10SrF2-10NaF-0.05PrF3 was equal to 1.19 x 10-7S/cm at 400K, and that the overall data could be described by:

σT (SK/cm) = 3.24 x 106 exp[-0.86(eV)/kT]
